SFM to RPM, Surface Feet Per Minute to Revolutions Per

The speeds shown are given in Surface Feet Per Minute (SFM) or Surface Meters Per Minute (m/min), measured at the periphery of thedrill. To calculate thedrill revolutions per minute (RPM) from the surface speeds, the following formulae should be used, where D=diameter of drill SFM = RPM x DIAMETER x 0.262 RPM = (SFM x 3.82) divided by DIAMETER

Common Formulas for Milling Operations Speed, Feed,

Milling Formulas. Speed (RPM) = (SFM x 3.82) / D. Feed (IPM) = RPM x FPT x Z. SFM (Surface Feet per Minute) = (RPM x D) / 3.82. IPT (Inches per Tooth) = (IPM / RPM) / Z. MRR (Cubic Inches per Minute) = IPM * WOC * DOC. AFPT (@ less than 1/2 dia. WOC) = IPM x sqroot of (D / WOC) HP (Horsepower Consumption) = MRR x mf. mf steel = 1.

Milling Speed and Feed Calculator How to Calculate CNC

The RPM calculated in the Mill Speeds and Feeds Calculator refers to the spindle speed in milling process, and IPM refers to feed rate. The exact RPM is not always needed, the following calculator (formula) may be used to estimate the value closely.
